Botany （植物学） , the study of plants, occupies a particular position in the history of human knowledge．For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest （模糊的）） of insights．It is impossible to know today just what our Stone Age ancestors knew about plants, but from what we can observe of pre-industrial societies that still exist, a detailed learning of plants and their properties must be extremely ancient．This is logical．Plants are the basis of the food pyramid for all living things even for other plants．They have always been enormously important to the welfare of people not only for food but also for clothing, tools, medicines, shelter, and a great many other purposes．Tribes living today in the jungle of the Amazon recognize hundreds of plants and know many properties of each．To them, botany has no name and is probably not even recognized as a special branch of "knowledge" at all．
Unfortunately, the more industrialized we become, the farther away we move from direct contact with plants, and the less distinct our knowledge grows．Yet everyone comes unconsciously on an amazing amount of botanical knowledge, and few people will fail to recognize a rose or an apple．When nor Neolithic ancestors, living in the Middle East about 10,000 years ago, discovered that certain grasses could be harvested and their seeds planted for richer fields the next season—the first, great step in a new association of plants and humans was taken．Grains were discovered and from them flowed the wonder of agriculture: cultivated crops．From then on, humans would increasingly take their living from the controlled production of a few plants, rather than getting a little here and a little there from many varieties that grew wild, and the accumulated knowledge of tens of thousands of years of experience with plants in the wild would begin to fade away．
1.What does the writer mean when he says "This is logical" in the first paragraph?
A．Human knowledge of plants is well organized and very detailed．
B．It is not surprising that early humans had a detailed knowledge of plants．
C．There is no clear way to determine the extent of our ancestor's knowledge of plant．
D．It is reasonable to assume our ancestors behave much like people in pre-industrial societies．
2.According to the passage, general knowledge of botany begun to fade away because ____．
A．people no longer value plants as a useful resource
B．direct contact with a variety of plants has decreased
C．botany is not recognized as a special branch of science
D．research is unable to keep up with the increasing number of plants
3.We learn that the first great step toward the practice of agriculture is____．
A．the changing diets of early humans
B．the development of a system of names for plants
C．the invention of agricultural implements （工具） and machinery
D．the discovery of certain grasses that could be harvested and replanted
4.Human would depend on the controlled production of a few plants for living with
A．the knowledge of plants
B．the discovery of certain grasses
C．the development of machinery
D．the appearance of agriculture

Have you wondered why different animals or pests have their particular colors? Colors in them seem to be used mainly to protect themselves.
Birds, especially seagulls are very fond of locusts, but birds can’t easily catch locusts because locusts change their colors together with the change of the color of crops. When crops are green, locusts look green. But when crops are ripe, locusts take on exactly the same brown color as crops have. Some other pests with different colors from plants are usually easily found and eaten by their enemies. So they have to hide themselves in terror for lives and appear only at night.
If you study the animal life in any part of the world, you will find the main use of coloring is to protect themselves, bears, wolves and other beasts move quietly through forests. They are usually invisible to the eyes of hunters, because they have the color much like the barks(树皮) of trees.
An even more strange act remains to be noticed. A kind of fish living in seas can send out a kind of very black liquid when it faces danger. While the liquid is over, its enemies cannot find it, and it quickly swims away. Thus, it has existed up to now though it is not powerful at all.
1.This passage mainly talks about ______.
A. the change of color in locusts
B. the protective coloration of animals and pests
C. how a certain sea fish protects itself
D. animals or pests can dye themselves different colors
2.Locusts are ______ but they aren’t easily wiped out(消灭)by their enemies because _______.
A. animals; they are powerful enough
B. beasts; they are dangerous to their enemies
C. pests; they take on the same colors as crops
D. birds; they fly very fast
3.What does the underlined word “invisible” in Paragraph 3 mean?
A. can’t be seen B. can be seen C. can’t move D. can’t change
